They might want to check the details first. They are not letting anyone but emergency responders in the immediate area right now. Some near by shelters may be accepting help. Idk.
From what I am seeing/hearing now a tank of chemicals combusted/exploded and the rain and wind seemed to knock down the the hazmat threat in the area. That is good news. The main problem they are having now is unstable structures that can not be searched. They have to attempt stabilization before they can enter.
